OHARCOAL OR OOKEOVEM sPEcIFIcArION forming part of Letters Patent No. 744,700, dated'November 17, 1903. Application am August z2, 190s. serial No. 170,412. '(N'o man.)

generated in the ovens.

My object is to burn and utilize such volatile matter for generating heat and thereby reducing the minimum of fuel required and lessening the cost of providing charcoal and coke.

My invention consists in the construction and operation of an oven as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in

which- Figure 1 is a horizontal sectional View of the structure that shows a plurality of arches in the floor, arched combustion-chambers, and a doorway at one end and horizontal flues and Aa chimney at the other end. Fig. 2 is a longitudinal sectional view in two parts on the line fr x of Fig. l and shows apertures under the arched iloor that allow communication between the combustion-chambers and the transverse flues under the floor and rear end of the oven and the chimney. Fig. 3 is a transverse sectional View on the line .e c of Fig. 2 and shows the position of the lfurnaces relative t0 the arched iloor and the openings that establish communication between the combustiOn-chamber and the space above and below the arched floor. Fig. 4 is avertical longitudinal sectional view through the middle of one of the furnaces and shows the passages that communicate with the horizontal flue.

The numerals 10 designate furnaces adapted for burning wood or coal located under the arched iioor 12 of the oven, and 13 represents arched tops over the furnaces that produce combustion-chambers that extend through and above the arched floor and rearward a short distance relative to the front wall 14E of the oven. The side walls are practically an arched roof 15, that is compact and closed from top to bottom and from front to rear.

The rear wall 16 has an integral chimney 17 and-below the arched iioorhorizontal flues 18, through which the waste products Ofcombustion pass from under the'floor to the chimney and escape therethrough.

A doorway 19 in the Acenter of the front wall 14 allowsA ingress and egress to the oven as required for filling in wood and coal and removing ch-arcoalandcoke `at different times. In the practical use of my invention when the oven is iilled with wood or coal and the doorway sealed and fires started in the furnaces and the fronts of the furnaces closed in any'suitable way, so as not to let too much air to the fuel, the fuel burned on the grates will generate heat suflicient tol rise from the combustionchambers and penetrate the combustible material in the oven and expel therefrom the gaseous matter, or all that can be volatilized, and produce a pressure that will force the volatilized matter or gases down into the combustion-chambers, where it will be burned and utilized in connection with the fuel on the furnace-grates for maintaining the requisite heat in the oven until the wood in the oven has beenconverted into charcoal or coal in the oven into coke.v After the combustible volatile matter is burned in the combustion-chambersthe smoke and waste products of combustion will pass through the apertures in the walls of the combustionchambers under the floor into the vacant space under the floor and then rearward into the horizontal flues iu the rear wall of the oven and then up and out through the chimney.

Having thus described the purpose of my invention and its construction and operation,

the practical utility thereof will be obvious to persons familiar with the artto which it pertains, and what I- claim as new, and desire to secure by Letters Patent, is- K v 1. In an oven for making charcoal and coke, a closed iioor, a closed wall above the floor, a furnace under the floor, a combustion-chamber extending through the licor and apertured for the passage of the products of combustion and the furnace apertured under the floor for communicating with an open space eX- tending under the floor in -the manner set forth for the purposes stated.

2. In an oven for making charcoal and coke, a closed iioor, a closed wall above the floor, a furnace under the floor, a combustion-cham- IOO roof closed from top to bottom and from front` to rear, a closed fioor, furnaces in the front Wall under the floor and communicating with an open space under the Hoor and combustonchamber extending; rearward from the front Wall and upward from the furnaces and provided with apertures cormnunicatingl With the chamber above the floor7 arranged and combined to operate in the manner set forth for the purposes stated.
